Toolbox and Fuel Tank Combos

It’s the all-in-one fuel tank and storage space!

Transfer Flow's toolbox and fuel tank systems are available in 30, 40, 50 and our
NEW 70 gallons, and are available for Dodge Ram, Ford and GM diesel pickups! They’re
the all-in-one auxiliary fuel tank and storage box! The toolbox fuel tank is computer
controlled, and the fuel transfer process is entirely automatic by our TRAX 3™ operating
system! The TRAX 3™ operating system comes with a dash-mounted LCD that show the
percentage of fuel in the main and auxiliary tanks. The LCD screen will also show
you when the fuel transfer is occurring.

The 30 and 50 gallon toolbox and fuel tank combos are made from bright aluminum
diamond plate, while the 40 and 70 gallon unit is made from aluminized steel and
is powder coated black (the lid on the 70 gallon combo comes standard with a diamond
plate lid). They come with all components needed for installation (some pickups
require a fillneck kit or tee). Our toolbox and fuel tank combos are fully baffled
to prevent fuel slosh, and should not interfere with most standard in-bed hitches.
The locking storage compartment will keep your every day work tools, RV supplies,
or hunting equipment safe and secure!

40 Gallon Toolbox and Fuel Tank Combo

Our 40 gallon toolbox and fuel tank combo is made from 14-gauge, black powder-coated
aluminized steel. The fuel fillneck is located inside the locking storage compartment
so both tools and fuel can be secured with the turn of a key. It has over 6 cubic
feet of storage space! It fits short bed and long bed pickups.

50 Gallon Toolbox and Fuel Tank Combo

Our 50 gallon fuel tank is constructed of 14-gauge aluminized steel and is mounted
inside the shell of the bright aluminum diamond plate toolbox. The fuel fill access
is on the driver’s side on the front of the toolbox. The locking storage compartment
has over 9 cubic feet of storage space! It fits long bed pickups only.

Caution

Gravity feed fuel systems may be easier to build and cheaper to buy, but does that
mean it’s the smart choice? Due to safety, environmental, and legal concerns, Transfer
Flow engineers will not endorse, promote, design, install, or sell gravity feed
fuel systems. On gravity feed systems, if the valves, connectors, or fuel lines
have any malfunctions there is nothing to stop fuel from overfilling the OEM tank
and leaking all over the road.

Transfer Flow Auxiliary Tanks Are NOT Gravity Feed Systems. Our tanks are NEVER
to be used in conjunction with gravity feed fuel systems.

Transfer Flow fuel tanks are NEVER to be used in conjunction with fuel tanks made
by other tank manufacturers. Our tanks are only compatible with your stock OEM tank
or Transfer Flow replacement tank.

Our two operating
systems:

The next generation of our TRAX auxiliary fuel tank operating system is here! TRAX
3™ is our computer controlled, self-diagnosing fuel monitoring system that transfers
fuel from your Transfer Flow auxiliary fuel tank to your main fuel tank. The LCD
displays the fuel level percentages in each tank and the operational status of the
fuel system. For your peace of mind, the TRAX 3™ computer module constantly monitors
fuel levels in both tanks.
